Shyvana changes very underwhelming
Shyvana jungle was never that great anyway she went entire seasons being ignored b/c she is a jungler who can't gank. Clear speed junglers who can't gank and can't secure kills to counter jungle will always lose to those who can in the most important stage of the game for a jungler: early game. And what does Shyvana get for her mad clear speeds and reaching a decent end game? Just that, a decent end game. She is no Yi or Udyr or even Warwick or Trynd who will get super strong late game and make a big impact. She was good top because she had game impact top. Your best prayer is counter ganking with her and hope your teammates aren't losing TOO bad or your effort will likely be wasted as your kited and/or they are killed when you don't have the cc to stop it from happening.
Look, Riot. Clear speed is not a valid strategy for a good jungler. Not alone.
Not only that but you NERFED her ITEMS. BOTH OF THEM FOR THE JUNGLE. And then you gave her a small small buff to her jungle clear speed, that even with that buff is slower than it was pre patch.
Would like to ask why you're complaining about a buff when everyone was affected by itemization changes.
